TEL-AVIV, Israel, March 7, 2014 (GLOBE NEWSWIRE) -- RedHill Biopharma Ltd. (Nasdaq:RDHL) (TASE:RDHL) (the "Company" or "RedHill"), an emerging Israeli biopharmaceutical company focused primarily on the development and acquisition of late clinical-stage, proprietary drugs for the treatment of inflammatory and gastrointestinal diseases and related conditions, today reported that it has secured direct rights from Temple University to the original RHB-102 patents, a once-daily oral formulation of the anti-emetic drug ondansetron.

As previously reported by the Company, SCOLR Pharma Inc. ("SCOLR"), which originally licensed certain patents to RedHill for RHB-102, announced that it had ceased business operations. Since SCOLR had itself licensed those patents from Temple University, the original owner of the patents, RedHill has now licensed those same patents directly from Temple University. The new licensing agreement with Temple University is under similar financial terms as the previous agreement with SCOLR, which has been terminated by RedHill.

The Company also reports that, following the completion of several previously-announces clinical studies, a pre-New Drug Application ("NDA") meeting was held with the U.S. Food and Drug Administration ("FDA") regarding RHB-102's development for chemotherapy and radiotherapy-induced nausea and vomiting ("CINV" and "RINV" respectively). Following the pre-NDA meeting, and in light of the FDA's feedback, RedHill provided the FDA with additional information and is currently awaiting the FDA's response. Given the ongoing discussions with the FDA, the Company believes that the NDA for RHB-102 will not be submitted in the first quarter of 2014 as planned. RedHill will provide an update on the expected timeline for NDA submission of RHB-102 as soon as sufficient regulatory clarity is obtained, based on the outcome of the discussions with the FDA.

In parallel to pursuing the CINV and RINV indications, RedHill is also pursuing a new indication for RHB-102. The Company expects that, if approved by the FDA, the new indication would significantly expand the potential market for RHB-102. To support the submission of an NDA targeting this additional new indication, RedHill is planning a Phase III clinical study later this year.

In parallel to advancing the regulatory pathways in the U.S. for multiple indications, RedHill also plans to submit, later this year, a Marketing Authorization Application ("MAA") for RHB-102 in Europe for CINV and RINV. RedHill plans to conduct a comparative bioavailability study comparing RHB-102 to a European reference product ahead of the MAA submission.

About RHB-102:

RHB-102 is a patent-protected, extended-release (24 hours) oral pill formulation of ondansetron, the active ingredient in GlaxoSmithKline's Zofran® immediate release tablets for the prevention of radiotherapy-induced nausea and vomiting ("RINV") and chemotherapy-induced nausea and vomiting ("CINV"). With clear potential advantages to cancer patients over the immediate release oral ondansetron tablets currently on the market, including the potential to enhance patient compliance and adherence thanks to increased convenience of use, RHB-102 is targeting a considerable segment of the 5-HT3 antiemetic market, estimated to have worldwide sales of approximately $940 million in 20131. RedHill has completed several clinical studies with RHB-102 and is developing the drug for multiple indications.
